318 head porting for the average joe
This is my first attemp at head porting. These are 1970 open chamber 318 heads. I did most of this work about two years ago and the heads have been sitting out in my shop since. There is a little flash rust on everything in the photos and the work you see here is not the finished product. I am an average Joe just trying to learn new stuff and do it on the cheap. 318 heads are like starfish; if you ruin one, another will grow back. I'm open to constructive criticism on the work you see here. Any helpful advice will be accepted graciously. There was a lot of seemingly excess material on roof of the exhaust port before. I don't know how much further you can go on these before you hit a water jacket. At this stage, I think I just need to smooth them out and call it good. The intake side ports have all been gasket matched and just need cleaned up. It looks like I could probably blend the guide bosses a bit more and smooth up the rest of the port. No valve job has been done here yet. If they turn out well, they'll end up on a mild performance 318 backed by a four speed transmission in a '66 Barracuda. Hopefully this will happen within my lifetime.:burnout:
